POSTER: Collaborative Authority-Based Searchable Encryption Using Access Control Encryption

In this poster, we propose a novel searchable encryption (SE) scheme that leverages access control encryption to enhance the security and flexibility of search operations. Our approach requires collaborative authority users to authorize data users for SE requests, ensuring that only authorized users can access the encrypted data. The proposed scheme utilizes keyword and collaborative authority user IDs as attributes in the access control encryption, allowing for the design of different search permissions tailored to specific use cases. We conduct a thorough correctness analysis to demonstrate the robustness of our approach.
